Common Air Conditioner Problems

Every homeowner has likely had to hire an HVAC technician for air conditioner repairs. And since AC units are crucial during summer, you must repair them on time. But what kind of problems do air conditioners face? This article will discuss the most common air conditioner problems in every home.  

Dirty Air Filters

Dirty air filters might seem like a minor problem, but it isn't. And since most people forget to swap their dirty air filters with new ones, their air conditioners will always experience efficiency issues. So, if you haven't changed the filter in months, your AC system will struggle to cool your home. Besides, the monthly cooling bills will also soar. Luckily, you can change air filters on your own without requiring the assistance of an HVAC expert.

Refrigerant Leaks

Refrigerant leaks also seem to be common in most homes. And since the refrigerant is responsible for cooling warm air, it's important to ensure that your refrigerant lines are always intact. Once the refrigerant begins to escape, your AC system can no longer provide cool air. As such, you must hire an air conditioner repair expert to seal the leaks and replace the lost refrigerant.

Frozen Evaporator Coils

Sometimes your air conditioner's evaporator coil may freeze and interfere with the supply of cold air. And since the evaporator coils play a massive role in cooling the warm air, the last thing you want is to have the coils freeze during summer. 

In most cases, evaporator coils freeze due to blocked air ducts, dirty coils, and clogged air conditioning drain lines. Call an HVAC expert to fix the issue if the AC unit isn't cooling or there is ice around the refrigerant lines and evaporator coil.

Failing Capacitors

Your AC system relies on capacitors to power the motors. So, if the capacitors fail, it would be impossible for the fans and compressor to work. That said, you must keep a close eye on your air conditioner's performance because it's the only way you'll know if the capacitors are faulty. AC units with faulty capacitors rarely run consistently. Besides, they will take time to power on. 

Drainage Problems

You must also watch out for drainage problems if you own an air conditioner. You should ensure the condensate drain works properly to avoid water damage to your AC system. Always confirm that the drain isn't clogged with dirt, lint, or dust. Also, ensure the drain pan is in good condition to avoid leaks.

Other problems to be wary of are electrical control issues, thermostat malfunctions, sensor problems, and compressor malfunctions.
